Я использую сервер удаленно через ssh и использую jupyter через туннель ssh.Я обычно могу заставить это работать, используя:
#!/bin/sh
sudo fuser -k 8881/tcp
echo 'Port 8881 is free now'
ssh -N -f -L localhost:8881:localhost:8888 myuser@serveraddress
read -p "Press enter to continue"
ssh myuser@serveraddress "sudo nohup jupyter notebook --no-browser"
wait
chromium http://localhost:8881/;sleep 1; exec bash &
Но, я не знаю почему, после некоторых обновлений и уничтожения некоторых портов, используя:
sudo fuser -k 8891/tcp
Где я это сделал си другие порты тоже.
Я пробовал команды типа (чтобы открыть):
sudo ufw allow 8891/tcp
Но теперь я получаю этот вывод при попытке использовать Jupyter удаленно:
sudo: no tty present and no askpass program specified
[8893:9160:0918/214007.129058:ERROR:token_service_table.cc(140)] Failed to decrypt token for service AccountId-114438117936628626704

И больше не могу запускать Jupyter.Кто-нибудь может мне помочь?Спасибо!
Сообщение: "sudo: нет tty присутствует и не задана программа askpass" Я получаю до этой проблемы, но, похоже, не проблема (как работало раньше, даже с этим предупреждением)).
ОБНОВЛЕНИЕ: Я запускаю его снова с -v -v в get:
